It is used where the space for the controls area is limited or crowded. The Mini is also popular with Jazz guitars using a floating pick-up. The smaller size gives it a nice minimalist touch. Also, savvy Strat players like to use a regular Dome for the volume control while using the Minis for the tone controls. It not only looks cool, but the extra space is very welcome.Standard size - designed to retrofit all imported and USA-made electric and bass guitars0.47 inches InlayComes with an Allen wrenchAll Q-Parts® Knobs are sold individually.
